Can I submit properties from Realtors that is listed on the MLS.

We have no objection to MLS or realtor listed properties, but you must have spoken to the realtor and determined that both the realtor and the owners are motivated to sell. 

We buy properties at whole sale prices. This is easier to achieve by taking directly to property owners rather than going through intermediaries. Realtors have no motivation to deal with investors that are looking for wholesale prices. Focussing on sellers and realtors that are not motivated will be a complete waste of your time and ours.
